Instagram official: Shawn Mendes unveils new girlfriend
Shawn Mendes seems ready to make that rumored romance official, doing it with an affectionate Instagram reveal.
The latest post on Shawn Mendes’ Instagram isn’t coy about what it is. For Bruna Marquezine’s 31st birthday, the singer stitched together clips of the two volunteering and hanging out at Casa Amarela Providência in Rio de Janeiro — a sun-soaked montage that reads like a soft launch turned full announcement.
“Eu te amo muito muito muitoo!!!”
He capped the tribute with that Portuguese declaration — “I love you so so much” — and praised the Brazilian actress as a light in every room who has changed his life. The post arrives as their relationship goes Instagram-official in August 2026 .
From sightings to soft launch
The birthday reel follows months of very public hints that something was up. Here’s the timeline fans have been tracking:
- 2017 — The two reportedly first crossed paths backstage after Mendes played Rock in Rio, and he followed her on Instagram soon after.
- March 2025 — Marquezine was spotted in the crowd during Mendes’ Lollapalooza Brasil set.
- November 2025 — They were photographed dancing and looking flirty at Dua Lipa’s concert in São Paulo.
- December 2025 — Dating buzz kicked up after affectionate outings around Rio de Janeiro.
- January 2026 — A cozy grocery run in Los Angeles kept the speculation rolling stateside.
- July 2026 — The pair resurfaced at a farmers’ market in Brazil, low-key but together.
- August 2026 — Mendes’ birthday tribute makes it social-media official.
For two people who kept it to glances in crowds and casual errands for months, the Rio charity footage plants a clear pin in where they are now — together, in public, and not hiding it.
The post’s location tag also underscores how much of their story has unfolded in Brazil, from that early festival overlap to recent time in Rio. And with the message arriving on Marquezine’s 31st, the couple’s first official milestone is stamped to a date: August 2026.
